FIELD OF THE INVENTION

[0002] The present invention is related to join metal component by punching connection, more particularly, related to force the metal of metal plate in corresponding the hole of metal component.

BACKGROUND OF THE INVENTION

[0003] In commonly know join for metal component to metal plate generally make use of products; for example, computer technology, which use new joint for metal component for new product. Thus, the connection of metal must be simple production and not be more expensive in manufacture than hitherto. As a result, the most direct and easy solution by using head type punch to forcing metal of metal plate into corresponding hole of metal component for joining metal plate and metal component with press-fit connection.

[0004] The conventional structure for joining metal plate and metal component are rivet joints. As shown in FIG. 1, that is constructed of rivet joint 1 with drilling of metal plate and metal component. It is complex, and resulting not only size of diameter and strength of material, but also wasting material consumption when drilling. Soldered connections require additional complex and costly manufacturing steps and may result in unreliable connections. Waste from the soldering process is hazardous to the environment and expensive to dispose of safely.

[0005] In view of the various disadvantages of conventional structure, the present invention addresses the disadvantages by researching solutions for them which, following continuous research and improvements, culminated in the method easy and convenient for joining metal component by press-fit connection of the invention herein, a method capable of eliminating the numerous drawbacks of the conventional technology.

OBJECT OF THIS INVENTION

[0006] Due to the continuous development of industry, production cost and mass production ability are always important. Thus, the improvement of manufacture is to be of great urgency.

[0007] Therefore, the main object of the present invention is to provide reducing production costs and fitting mass production for connection of metal.

[0008] Another object of the present invention is to provide location mark and fixture for press-fit connection by head type punch.

SUMMARY OF THE INVENTION

[0009] Specifically, the present invention provides a method for joining metal component by press-fit connection characterized by at least one hole of metal component place in inner channel of metal plate by using head type punch to forcing metal of metal plate into corresponding hole of metal component for joining metal plate and metal component with press-fit connection

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be better understood from the following detailed description of preferred embodiments of the invention, taken in conjunction with the accompanying drawings, in which

[0011]FIG. 1 is a perspective diagram of joining metal plate and metal component with rivet joint in accordance with the conventional structure;

[0012]FIG. 2 is a perspective diagram of joining metal plate and metal component with press-fit connection in accordance with the present invention; and

[0013]FIG. 3 is a perspective view of procedure of press-fit connection in accordance with the embodiment of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] According to the disadvantages of conventional fastening structure as described above, the present invention provides an improvement solution for that. Embodiments of this invention will be described in detail with reference to attached drawings.

[0015] Please referring to FIG. 2 joining metal plate and metal component with press-fit connection in accordance with the present invention, it provides at least one hole 22 of metal component 21 place in inner channel 13 of metal plate 11 by using head type punch 41 to forcing metal of metal plate 11 into corresponding hole 22 of metal component 21 for joining metal plate 11 and metal component 21 with press-fit connection.

[0016] Please seeing the FIG. 3 of procedure of press-fit connection in accordance with the embodiment of the present invention; first, it makes the location mark 23 of hole 22 on the metal component 21; next, the metal component 21 and metal plate 11 use the fixture 31 to achieve automatic location for placing metal component 21 in the inner channel 13 of metal plate 11; finally, according to location mark 23, it use head type punch 41 to forcing metal of metal plate 11 into corresponding hole 22 of metal component 21 and generating punch concave mark 12 for joining metal plate 11 and metal component 21.

[0017] Besides, the present invention of the hole 22 of metal component 21 is applied to circle or long-circuit sharp to satisfy mechanical error and metal plate 11 is a copper plate. please referring to FIG. 3, this invention further comprises location mark 23 and fixture 31. However, as the person skilled in the art may disclosure for increasing or decreasing the part of method for easy operation.

[0018] In summation of the foregoing section, the invention herein fully complies will all new patent application requirement and is hereby submitted to the patent bureau for review and the granting of the commensurate patent rights.

[0019] The present invention may be embodied in other specific forms without departing from the spirit of the essential attributes thereof; therefore, the illustrated embodiment should be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
